Abstract
AbstractThis paper demonstrates the comparative analysis of the performances of two antenna designs, half wavelength Wireless Local Area Network (WLAN) patch antenna and a broadband Ultra wideband (UWB) monopole antenna. Both the antenna designs have been simulated utilizing the Advanced Design System (ADS) tools. During the investigations, it has been observed that the low profile antenna with its wide impedance bandwidth, quasi-Omni directional radiation pattern and high efficiency is quite promising for the existing communication and surgical instruments. In this work, we have simulated and measured the different essential parameters such as input reflection; voltage standing wave ratio (VSWR), radiation pattern, simulated current distributions and the efficiency of the proposed designs are also presented and analyzed. Measured results were taken using a Vector Network Analyzer (VNA).KeywordsVoltage standing wave ratiobroadband antennaInput reflectionlow profileEfficiencyImpedance bandwidth
